BISTEL ESQUIVEL, Roberto A.; FAJARDO MARQUEZ, Ariel; FERNANDEZ SIGLER, Arlem L.  e  VALDES ZALDIVAR, Enrique E.. Design of a Virtual Instrument for the calibration of Electrocardiography Systems. EAC [online]. 2013, vol.34, n.2, pp. 19-35. ISSN 1815-5928.

This article reports the main elements of design and development of a system to generate the calibration signals for electrocardiography indicated in the rules of the International Electrotechnical Commission (IEC). The ECG simulator and IEC's calibration signals are necessary to test, calibrate, evaluate, faultfinder and perform maintenance and repair Electrocardiographic Equipment. The application relies on the use of a software tool based on the principles of the Virtual Instrumentation, which manages hardware resources (DAQ NI PCI-6229 and external electronics circuits) as an interface between the workstation and equipment to check. The initial estimated cost of research and development of prototypes is significantly reduces with the serial production of the respectively modules. This allows for lower cost units to commercial simulators counterparts, typically ranging about $ 1200 USD. The simplicity and advantages of this new system respect to classical ECG generation allows for the implementation of the tool in the evaluation and calibration activities, and make available its generalization in all the technical services responsible for providing maintenance of Electrocardiographic Systems.
